working with operators

Again having a problem with a code .... and can't figure out the right result ... the code is right a syntax ( checked it in xcode ) but the site is returning an error message that i have to assign the results of a comparison to isGreater constant which i declared earlier and not just a bool value ...

operators.swift
// Enter your code below
let value = 200
let divisor = 5

let some0peration = 20 + 400 % 10 / 2 - 15
let another0peration = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below
let result = 5 % 7
let isPerfectMultiple = result == 0
// Task 2 - Enter your code below
let isGreater = some0peration <= another0peration 
isGreater = true

There are two problems with your code. The first one being that you have changed the name of the someOperation and anotherOperation (With a capital O) to some0peration and another0peration (with the number 0). Changing the name of constants or variables setup by the challenge is usually a bad idea and will often break the challenge.

The other problem is that you use the wrong comparison operator, you use <= which is less than or equal to. You are meant to use >= which is greater than or equal to.

If you fix those errors and remove your last line since it's uneccesary and incorrect since you can't reassign a constant, like this:

// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below
let result = 5 % 7
let isPerfectMultiple = result == 0
// Task 2 - Enter your code below
let isGreater = someOperation >= anotherOperation

Then your code will pass.
